Abstract
An automatic drawing apparatus wherein coordinates of dots are determined on the basis of allocation data of unit dot patterns each consisting of one- or two-dimensional dot allocation and data of a reference line obtained by one-dimensionally allotting the unit dot patterns. A dot pattern is plotted on the basis of dot outline data and their coordinate data, thereby producing a high-precision pattern image within a very short period of time.
